A series of substituted benzoate-bridged dichromium(II, II) complexes [Cr-2(RCO2)(4)(THF)(2)] ([Cr-2]), where RCO2- is substituted benzoate, was synthesized and its structural and magnetic properties were investigated. The orbital energies, as well as magnetic coupling energies, were also investigated using computational approaches. The HOMO/LUMO energy levels of the complexes are strongly dependent on the acidity, i.e., pK(a), of the corresponding benzoic acids (RCO2H), revealing a linear trend in the respective groups of non-ortho, mono-ortho, and bi-ortho substituted groups. The Cr center dot center dot center dot Cr magnetic coupling constant (E-S (T)) is little affected by pK(a); instead, the E-S (T) is associated with the HOMO/LUMO gap and strongly correlated with the Cr center dot center dot center dot Cr distance.

Competitive reactions, on the surface of plasmonic nanostructures, allow exploiting SERS signals for quantitative Therapeutic Drug Monitoring. As an example, the concentration of Erlotinib, an anti-EGFR small molecule, used for the treatment of non-small cell lung and pancreatic cancer, is determined. The numerous side effects and the variability of patient responses make Erlotinib a good candidate for monitoring. The new SERS based sensor can estimate Erlotinib down to nanomolar concentration and is based on the chemical reaction of the drug and of a competitor SERS reporter on the surface of gold nanostructures. Colloid solutions of naked gold nanoparticles obtained by laser ablation in solution were used for obtaining nanostructures with very efficient hot spots for SERS and with a clean surface for chemistry. Detection of the drug in the nanomolar concentration range is shown to be possible also in spiked plasma samples. (C) 2018 Elsevier Inc. All rights reserved.

Synthesis of a series of 3,6-disubstituted-bis-1,2,4-triazolo-[4,3-b][3′,4′-f]pyridazines (4) was accomplished by the oxidative intramolecular cyclization of 6-arylidenehydrazino-3-aryl-1,2,4-triazolo[4,3-b]pyridazine (3) using iodobenzene diacetate (IBD), as a green oxidant, in dichloromethane at room temperature. The compounds 3 and 4 were characterized by IR, NMR (H-1 and C-13), mass spectral data and elemental analyses. X-ray crystal analysis of sterically strained 3,6-di-(2′-fluorophenyl)-bis-1,2,4-triazolo-[4,3-b][3′,4′-f]pyridazine 4f and 3,6-di-(4′-fluorophenyl)-bis-1,2,4-triazolo-[4,3-b][3′,4′-f]pyridazine 4g indicated that pyridazine ring has twisted conformation leading to nonplanar tricyclic core. Both compounds crystallized in orthorhombic P2(1)2(1)2(1) space group, containing one single molecule per asymmetric unit. The studies reveal that the compound 4f is associated with weak, centrosymmetric F center dot center dot center dot F interactions (distance of 2.882(3) angstrom), with cis geometry, between adjacent molecules which are responsible for the formation of chains along a axis. Additionally, compounds 4 were screened for their cytotoxic activity against the human cervical carcinoma (HeLa) cell line using MTT assay, however, with not much significant activity.

The reaction of zirconium salts with meso-tetra(4-carboxyphenyl)porphyrin (TCPP) in the presence of different modulators results in the formation of a diverse set of metal-organic frameworks (MOFs), each displaying distinct crystalline topologies. However, the synthesis of phase-pure crystalline frameworks remains challenging due to the concurrent formation of different polymorphs. The acidity and concentration of the modulator greatly influence the outcome of the MOF synthesis. By systematically varying these two parameters, selective framework formation can be achieved. In the present study, we aimed to elucidate the effect of modulator on the synthesis of zirconium-based TCPP MOFs. With the help of powder X-ray diffraction and scanning electron microscopy, modulator candidates and the optimal synthetic conditions yielding phase-pure PCN-222, PCN-223, and MOF-525 were identified. H-1 nuclear magnetic resonance analysis, thermogravimetric analysis, and N-2 gas sorption measurements were performed on select MOFs to gain insight into the relationship between their defectivity and modulator properties.

Taking advantage of the differentiating effect of the solvent methanol, deuterations of electron-rich aromatic systems can be carried out under mild acid catalysis and thus under far milder conditions than known so far. The exceptional functional group tolerance observed under the optimized conditions, which even includes highly acid-labile groups, results from a hitherto unexploited shifted selectivity in protonation, and enabled simple and straightforward access to complex deuterium-labeled compounds.

Polyfunctional arenes are an important part of the chemical value chain. To improve the efficiency of their synthesis, we have investigated a multicomponent approach built upon the Catellani platform. Here, we describe a 4-component coupling of aryl iodides lacking an ortho substituent that installs 3 discrete functional groups on the arene in a single step. The process is regio- and chemoselective and uncovers remote substituent effects that have a pronounced influence over inter mediate Pd-(II) complexes. These intermediates have been a long-standing focus of the Catellani-reaction development, but persistent challenges have given rise to the well-known ortho effect. We now show that the ortho effect can be a positive element of reaction design, and that previously problematic iodides can now be used in complexity-generating transformations. In expanding the scope of the Catellani platform, we hope to provide mechanistic considerations to guide future reaction design, while also improving the environmental footprint of synthesizing polyfunctional arenes.

A safe and scalable continuous flow strategy for Wolff-Kishner reductions that employs methanol as the solvent has been developed. The use of low-cost hydrazine as the reducing agent in combination with a caustic base provides an atom-efficient, environmentally friendly method for the deoxygenation of aldehydes and ketones to alkanes. Because of the required harsh and corrosive reaction conditions (200 degrees C, 50 bar), reactor materials such as stainless steel, glass, or any type of polymer have compatibility problems, rendering this process problematic on a production scale. The use of corrosion-resistant silicon carbide (SiC) as the reactor material opens up the possibility of performing Wolff-Kishner reductions on scale with a considerably improved safety profile. Methanol as the solvent significantly simplifies the workup procedure compared with the generally employed high-boiling solvents such as diethylene glycol. The continuous flow protocol was applied to a number of substrates and provided the desired products in good to high yields with space-time yields of up to 152 g L(-1)h(-1). In addition, a pharmaceutically valuable active pharmaceutical ingredient precursor was synthesized by employing this high-temperature/pressure Wolff-Kishner protocol.

A novel, quick, environmentally safe, and one-pot synthesis of a series of N,N-bis(cyanoacetyl)hydrazine derivatives, bis-imino-2H-chromenes and bis-2-oxo-2H-chromene derivatives have been designed. Some selected newly synthesized compounds were investigated in vitro for their antibacterial activity. Compound 5j is the most toxic compound against Staphylococcus aureus with activity index 171%, followed by compound 15b with activity index 136% compared to standard drug ampicillin. Moreover, compound 15a is the most toxic compound against Escherichia coli with activity index 111% compared to standard drug gentamicin. Minimum inhibitory concentration (MIC) was carried out for compounds with high antibacterial activity. Compound 5j has good MIC (7.8 mu g/ml) against Staphylococcus aureus while 15a has good MIC (31.25 mu g/ml) against Streptococcus mutans which is better than MIC of the standard drug ampicillin (MIC = 62.5 mu g/ml). Compounds 5j, 5k, 15a, 15b and 15e which have good MIC values were introduced to enzyme assay against DNA gyrase and topoisomerase IV. The results showed that compound 15a can strongly inhibit DNA gyrase and topoisomerase IV (IC50 = 27.30 and 25.52 mu M respectively), compared to methotrexate as the standard drug (IC50 = 29.01 and 23.55 mu M respectively). Structure-activity relationships were also discussed based on the biological and docking simulation results.
